Application filed June 25, 1903. Serial No. 163,055. (No model.)

To allwhom, it may concern:

Be it known that I, DOUGLAS S.DUFUR, a citizen of the United States,residing at The Dalles, in the county of Wasco and State of Oregon,

have invented certain new and useful Improve:

A further object of my invention is to provide a line-number andsheet-length indicating and alarm device and a slide-scale for.measuring any margin desired at the top or other part of each sheet. 7

While of more general application, my incable to type-writing apparatus.

To these ends my invention consists in the construction, combination,and arrangementof parts hereinafterdescribed and claimed.

Referring to the drawings forming a partof. this application and inwhich similar ref-i 'erence-letters indicate corresponding parts in theseveral views, Figure 1 is a perspective view showing my inventionapplied to a typewrltmg machine. Fig. 2 is an elevation, on a largerscale, of the pneumatic means for ac tuating the type-writer carriage,the paper reels, and the indicatingdevice. Fig. 3 is an axial sectionalview of one of the take-off reels. Fig. 4 is an end elevation, partlybroken away, showing the arrangement of the guide and tension rolls.Fig. 5 is a central vert cal section showing the plston-valve and itsconnections.

Fig. 6 is a rear elevation, partly broken away, showlng the mechanlsm isa rear elevation of the indicating and alarm device. Fig. 14 1s a detailview showing in side elevation the relative position of certain elementsof the indicating and alarm device, and Fig. 15 is a side view of aslide-scale for measuring the margin desired at the top of a sheet. Fig.16 is a detail view of the carriageactuating means.

Referring particularly to Fig. 1, A represents a base having suitablesupports a a; B is a conventional representation of a typewriter, thekeyboard and certain details being omitted for clearness. Upon thetype-writer frame B is supported the usual carriage B carrying theplaten B Pivoted to the under side of the base A is a swinging arm 0,.provided at its lower end with a stirrup C. A single-acting pneumaticcylinder D, conveniently attached to one of the supports a, is

provided with the usual piston and piston-rod D. The forwardcylinder-head may be provided with apertures D and any well-known formof valved piston employed. The outer end of piston-rod, D carries across-head D arranged to travel on the guides D as clearly shown inFig. 1. The swinging arm C is operatively connected to the cross-head bythe slot C in said swinging arm, which encom-- passes a pin on thecross-head. Through the rear head of cylinder D are tapped the pipes Eand F. The pipe F is open to the indicator I and to a pneumatic cylinderH, supported on the type-writer frame B, and the pipe E communicateswith the piston valve J, as shown especially in Figs. 1, 2, 5, and 10. Apipe K establishes free communication between the piston-valve J and acylinder L, carried by the base A for actuating the rotating mechanismof the take-01f reels. As shown in Fig. 5,-the piston-valve J embodiesthe cylinder J, piston J piston-rod J an inlet E, and an outlet K. Inthe position shown the pipes E and K are in communication; but by movingthe piston J 2 to a position intermediate the pipes E and Kcommunication between said pipes will be interrupted.

Referring now especially to Figs. 1, 6, 7, 8, and-9, the cylinder L isprovided with a piston L and piston-rod L carrying a rack L The rack Lis guided in constant mesh Wit a pinion M, which pinion, together withits retaining-plate M is rigidly secured to the barrel M. The barrel andattached pinion are loosely mounted on a shaft M, which is held fromturning in its bearings M M by any suitable means, as a key M. Thebarrel incloses a spiral spring M one end of which is secured to thebarrel at M and the other end connected to the shaft M at M. Aratchet-wheel M and bevel-gear M are rigidly secured together andloosely mounted on the shaft M. A pawl M pivotally secured to theretaining-plate M engages ratchetwheel M upon the rotation of the barrelM by the spring M but slides over said ratchetwheel on the reversemotion of said barrel during the winding up of the spring M Abevel-pinion M is secured to a shaft M in mesh with the bevel-gear M".The shaft M is rotatably supported in brackets M M and carries asuitable number of disks M, rigidly secured thereto, as by pins M.Knurled nuts M are threaded on shaft M adjacent to the disks M forconfining one end of springs M and adjusting the tension of saidsprings. bear against bevel-pinions l loosely mounted on the shaft M.Interposed between the disks M and bevel-pinions M are frictiondisks Mpreferably of leather, against which the bevel-pinions are held with apressure regulated by the tension of springs M Meshing with eachbevel-pinion M is a bevel-pinion O, secured to a short. shaft 0,journaled in a bracket O A plurality of shafts O are journaled in thebracket 0 and arranged parallel to the shafts O, with which they areoperatively connected by intermeshing gears O Each of the shafts O Ocarries means 0, preferably a flat bar, for supporting and rotating thetake-off reels 0. The bracket 0 is provided with guide-rails O and O forthe traveling carriage O. The traveling carriage comprises two endmembers 0, between the lower portions of which are carried thefeed-reels O. A bracket 0 is secured to traveling carriage 0 adjacent tothe feedreels 0. This bracket is provided with members 0, having slots 0arranged to receive the end journals of a plurality of tension and guiderolls 0. Springs 0 are shown embracing the end journals of thetension-rolls O for maintaining the periphery of such rolls in yieldingcontact. The take-off reels 0 are preferably arranged in the upperportion of the traveling carriage O and are supported at their left-handends by spring-pressed pins 0, shaped to fit sockets in said rolls. Eachreel O is provided with an axial bore 0, into which fits one of the flatbars 0, the reel being arranged to slide longitudinally on said bar andto rotate therewith. The flat bars O pass through openings 0 in therighthand member 0 of the traveling carriage, such openings beingsufiiciently large to per- The other ends of the springs M mit freemovement of the bars therein. A rod H connects the traveling carriage 0with the piston-rod H of pneumatic cylinder H. The piston-rod H is alsoconnected by a resilient link H to a shaft H, which is journaled in abearing H carried by a rod H, mounted to slide in the supports H. Theend of said shaft is also journaled in a bearing H", which is supportedon a pivot H arranged on the carriage axially with relation to thetype-writer platen. The shaft H is shown carrying a pawl H, which isconstructed to rotate the type-writer platen for line-spacing; but thisconstruction constitutes no part of applicants invention as claimed inthis application and need not be further described.

Referring especially to Figs. 10, 11, 12,13, and 14:, the indicating andalarm device I is provided with a front dial P, having any desirednumber of divisions and a pointer P. The pointer P and theratchet-wheels P P are rigidly secured to a central spindle P and saidspindle extends beyond the rear of ratchetwheel P sufficiently toreceive the boss P of the adjustable part P", as clearly shown. Theadjustable part is provided with a tappet P and carries a pawl P pivotedto it at P, and adapted for engagement with ratchet-wheel P. Anextension of boss P is mounted to turn in the rear cover-plate P, and anauxiliary pointer P is secured to said boss adjacent the rear side ofsaid cover-plate. A yoke S is carried by the piston-rod S of a piston Sand is providedwith a guide-lug S. A spring-pressed pawl S is secured toyoke S in position to engage ratchet-wheel P". A springpressed detent Sis pivoted tothe indicatorframe and also engages ratchet-Wheel P Analarm-bell S is mounted above the indicator, and a hammer S is pivotallyconnected at S to the indicator-frame in operative position with saidbell. The lower portion of said hammer constitutes a pendulous latch S",which is arranged to be engagedby the tappet P or by a tappet P onratchet-wheel P The latch S is provided with a shoulder adapted tocompress a spring S to augment the'striking effect of the hammer. Thedownward movement of piston S may be effected by gravity or by a springS, secured to said piston and to a pin S Such downward motion of thepiston may be limited by a shoulder S. A slide-scale T is secured to thetype-writer carriage by a screw T and is shaped to approximately followthe periphery of the type-writer platen. This scale is provided withdivisions corresponding to line-spaces and carries an adjustable slidemember T When using the slide-scale, the slide T is set at that numbereddivision corresponding to the number of linespaces which it is desiredto leave as a margin at the top of a sheet. When the indicating andalarm device indicates that the last line on a sheet has been written,the type-writer .following sheet.

platen is rotated to bring such last-written line up to said slide Tthus securing the desired space between the last-written line and thefirst line of the following sheet.

The operation of my apparatus is as follows: Feed-reels 0, containingrolls of paper and transfer-paper, are placed in the lower portion oftraveling carriage O and arranged to secure a sheet of transferpaperinterposed between adjacent sheets of paper. The several sheets are thenled between the guide and tension rolls, the sheet from the bottom reelbeing led between the first and second tensionrolls from the bottom, thesheet from the second reel from the bottom being led between the secondand third tension-rolls, &c., as shown in Figs. 1 and 4. Thetension-rolls prevent slack in the paper-supply and insure an evenunwinding of the feed-reels O. The sheets are then carried between theusual platen and pressure-roll of the type-writer, partly around theplaten, and finally to the take-off reels 0, as shown in Fig. 1. Theoperator then slides the platen, together with the attached travelingcarriage 0, to proper position and writes the first line of type-writingin the usual manner. After a line of desired length has been typewrittenthe operator actuates the swinging arm 0 with his foot to temporarilycompress air in the rear end of cylinder D. Through the pipe F pressureis communicated from cylinder D to the pistons H and S This pressureforces the piston H to the right,.carrying with it the type-writerplaten and the traveling carriage 0 thus bringing them into properposition for the operator to start on the next line of type-writing.This movement of piston H also turns the type-writer platen forline-spacing by means of connecting mechanism H but as this mechanism isclaimed in a copending application, Serial No. 145,607, and forms nopart of the invention claimed herein it need not be further described.These steps'are repeated until the end of the sheetis reached,when theoperator turns the type-writer platen by hand sufliciently to providefor the desired margin at the top of the The margin is measured by thesliding scale T, as hereinbefore described. Before beginning to write,the operator sets pointer P to the division numbered l on the dial P,and each time air is compressed in the cylinder D to return thetype-writer platen into position for beginning a new line the pressurecommunicated through pipe F to piston S will actuate said piston and itsattached yoke S, thereby rotating the ratchetwheel P sufficiently tomove the pointer P to the. next higher division on dial P. When thepointer P reaches the highest division on dial P, the tappet P will triplatch S and ring. the alarm-bell S If it is desired to have thealarm-bell sounded after any particular number of lines have beentype-Written, the pointer P is set to the correspondingly-numbereddivision on the back cover-plate P which will bring the tappet P intoposition to trip the latch S at the desired point. The piston-valve isnormally set to permit communication between the pipes E and K, as shownin Fig. 5, thus causing the piston L to be actuated each time air iscompressed in cylinder D. Each time the piston L is so actuated itforces forward the rack L and places spring M under tension, and uponthe relief of pressure in cylinder D the spring M un- Winds, therebyreturning the rack L and piston L to their initial position, ready to be7 again actuated by compression of air in cylinder D.. The spring inunwinding rotates the shaft M through the intermediary of pawl M ratchetM and bevel gears M M as hereinbefore described. Such rotation of shaftM tends to rotate the bevelgears M held by springs M againstfriction-disks M of said shaft, and thus to wind up the paper on thetake-off reels supported on flat bars 0*. Should, however, theresistance of any take-up reel become abnormal, the correspondingbevel-gear M will slip against its friction-disk, and thus prevent anytearing or injury of the paper.
